Subject: [PATCH rc] iommu/tegra241-cmdqv: Fix missing cpu_to_le64 at lvcmdq_err_map
Date: Thu, 14 Aug 2025 12:30:38 -0700 [thread overview]
Message-ID: <20250814193039.2265813-1-nicolinc@nvidia.com> (raw)
Sparse reported a warning:
drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:305:47:
sparse: expected restricted __le64
sparse: got unsigned long long
Add cpu_to_le64() to fix that.
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202508142105.Jb5Smjsg-lkp@intel.com/
